What XML schema defines the document's format?

Without knowing the schema, parsing will be unreliable.

What created the document? Why is it relevant that the document was
“created from CSV”?

What do you mean by “attributes”?

In Python, an attribute has a specific meaning.

In XML, an attribute has a rather different meaning.

Neither of those meanings seems to apply to “the XML document has three
attributes”. XML documents don't have attributes; differnt XML elements
in a document have different attributes.

How are those defined in the document's schema?

You should:

* Learn some more about XML
  <URL:http://www.xmlobjective.com/the-basic-principles-of-xml/>.

* Learn exactly what formal document schema defines the document
  <URL:https://en.wikipedia.org/wiki/XML_schema>. If the document isn't
  accompanied by a specification of exactly what its schema is, you're
  going to have a difficult time.
